Influence of the frame size on splitting ratio in the passive optical networks XG-PON
Kočí, Lukáš ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
The diploma thesis deals with the theoretical definition of passive optical networks, furthermore the description of methods of channel bundling in passive optical networks and the coexistence and migration between standards. The main essence of this work is the XG-PON (10-Gigabit-capable Passive Optical Network) standard. This standard is generally defined along with a description of the physical layer. The transport layer is detailed analysis. There is a description of conditions, under which the Optical Network Unit pass through, when is activated. Additionally, this diploma thesis focuses on the processes of connecting Optical Network Units to the Passive Optical Networks and the timing relationships between Optical Network Units and Optical Line Terminal. The simulations demonstrate that as the number of simultaneous connections to Optical Network Unit increase, longer wait time for each additional connection becomes. This also solves the collision conditions, that might arise in communication and the equalization delay. Finally, the diploma thesis deals with the influence of a refractive index on timing relationships.

Impact assessment of split ratios on passive optical network
Gallo, Martin ; Kočí, Lukáš (referee) ; Horváth, Tomáš (advisor)
This thesis deals with the most recent passive optical network standard NG-PON2, describes the sublayer model which includes error correction coding during propagation in optical fibres. Assesses the impact of split ratios using the simulation environment created from defined model and compares various scenarios. Discusses possible sources of errors of simulation model in compare to real deployment.
